Is this reverting
"f07aa795c92a ("net/qede: disable per-VF Tx switching feature")"
This will be same as code before f07aa795c92a , right? If so why not just remove
the config option for this release and add a dynamic runtime in next release?
I am not clear for both f07aa795c92a and this one fixing, and why should they be
included for rc3?
Thanks,
ferruh

Hi Ferruh,
Some customers are interested in getting better performance with 64B sized
packets. For that, they would need to keep this config disabled.
But in all other cases, by default, we would like to keep Tx switching
enabled (at a reduced performance) as in previous releases.
As stated in other email with Thomas, we shall remove this compile-time
config option in next release and use runtime option instead.
But for 17.08 we need it to be enabled by default.
Thanks.

Correction, I meant 17.11 release, not 17.08.

Other patch just sent two days ago, to introduce the config option as disabled
by default, so it was changing the behavior and accepted as a fix for rc3.
Now two days later, this patch enables it as a fix again, only difference for
two days ago becomes adding a config option?

Hi Ferruh,
The patch sent two days ago with config option disabled was a mistake.
Yesterday we realized that it is not a desirable thing to keep the config
disabled since many customers would typically need Tx switching to be
enabled.
So the current patch we sent is just to change back the config option set
to enable from disable. Hence its a fix for the previous patch.
Thanks.

I am trying to say, if you want to revert back and turn to original code, why
not completely revert, removing config option too?
Specially taking into account that you will remove it next release already.

The cumulative output of both patches are adding a config option that doesn't
change code execution by default. Overall output is not a fix.
What do you think about a full revert of previous patch?

We have an issue where we see low numbers with 64 byte frames and is seen when "per-VF Tx switching" feature is enabled (which is the default behavior without the config option). To get better performance with small sized frames, the fix is to disable the Tx switching feature. We need to have the config option as a hotfix as it provides a means to disable "per-VF Tx switching" feature and achieve better performance with small sized frames. In other words, it provides end user with an option to enable a feature or get better small packet performance.
We also need this config option to be picked in DPDK 17.08 stable, which exhibits same behavior.
Thanks!

I got what you are doing, this is about how you did it, but ok to patch, I think
already late to discus more.

Not sure if we backport new config options to stable trees? cc'ed Yuanhan.
